To aZL whom, it may concern:

Be it known that I, BENJAMIN F. MAYO, a citizen of the United States,residingat Salem, in the county of Essex and State of Massachusetts,have invented certain new and useful Improvements in Sole-PressingMachines; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

The present invention relates to sole-pressing machines of that typeWhich comprise a plurality of shoe-supporting jacks and cooperatingforms and in which means are provided for connecting and disconnectingthe actuating mechanism and each jack and its cooperating form in orderthat a jack may always be in a position of presentation to allow theoperator to remove a shoe which has been operated upon therefrom and toplace another shoe thereon.

The object of the present invention is to provide means for actuatingthe devices by which each jack and its cooperating form is operativelyconnected to the actuating mechanism, whereby the proper actuation ofeach jack and form is insured and any liability of the jacks and formsbeing displaced during the operation of the machine, so as to causeinconvenience to the operator or injury to the lasts or the mechanism ofthe machine, is avoided.

With this object in view the present invention contemplates theprovision in a machine of the type referred to of means under thecontrol of the operator for positively actuating the connecting devicesto operatively connect each jack and its cooperating form to theactuating mechanism. By providing means for positively actuating theconnect ing devices a complete movement of the con necting devices intooperative position is in sured, and any liability of a jack and formbeing disconnected from the actuatingmechanism until the cycle ofoperations of the machine has been completed is avoided.

The present invention also contemplates the provision in a machine ofthe type referred to of means whereby when one of the connecting devicesis positively actuated to operatively connect a iack and itscooperati-ng form to the actuatlng mechanism all the otherconnectingdevices are moved to inoperative position, so that by nopossibility can more than one jack and its cooperating form be connectedto the actuating mechanism at the same time, and any accidentaldisplacement of the jacks and forms which the operator does not intendto throw into operation is prevented.

In the preferred form of the invention the connecting devices arepositively actuated through connections to the starting treadle ortreadles, by which the actuating mechanism is thrown into operation. Inthe machine hereinafter described as embodying the various features ofthepresent invention in their preferred form the connecting devices arein the form of latches, and the latches are so connected that when onelatch is in operative position the other latches are held in inoperativeposition. A starting-treadle is provided for each jack and itscooperating form, and each treadle is connected to a latch in such amanner that each latch can be moved into operative position by thetreadle connected thereto and simultaneously all the other latches movedinto inoperative position.

In addition to the features of the invention above referred to thepresent invention consists in certain devices, combinations, andarrangements of parts hereinafter described and claimed, the advantagesof which will be obvious to those skilled in the art from the followingdescription.

The various features of the present invention will be clearly understoodfrom an inspection of the accompanying drawings, in which Figure 1 is aview in side elevation of a well-known form of sole-leveling machine.Fig. 2 is a view in rear elevation of the machine illustrated in Fig. 1with certain parts omitted to avoid confusion in the drawing. Fig. 3 isa sectional plan view illustrating the mechanism in the lower portion ofthe machine-frame by which the cam-shaft is thrown into and out ofoperation. Fig. 4 is a detail plan view, on an enlarged scale, of aportion of the mechanism illustrated in Fig. 3. Fig. 5 is a view in rearelevation of the mechanism illustrated in Fig. 4. Fig. 6 is a view inside elevation of a portion of the machine illustrated in Fig. 1,showing the application of the present invention to the machine; andFig. 7 is a view in front elevation of the parts illustrated in Fig. 6.

The machine illustrated in Figs. 1 to 5, to which the preferredembodiment of the present invention has been applied, is a sole-levelingmachine of the so-called direct-pressure type, in which a relativevertical movement is imparted to the jacks and forms to produce pressureupon a sole and in which horizontal movements are imparted to the jacksto bring them from a position of presentation at the front of sition inline with their cooperating forms and to return them to their positionof presentation. In this machine the connecting de vices for connectingeach jack and its cooperating form to the actuating mechanism arearranged to connect the jacks to the mechanism by which they are movedhorizontally, each jack when the connecting device associated therewithis in operative position being moved horizontally at the proper timesduring the operation of the machine, while the other jack remains in itsposition of presentation. While, however, the invention has beenillustrated as embodied in a machine in which the jacks and forms areactuated as above described, it is to be understood that the inventionis not limited to use in a machine in which the jacks and forms are soactuated, but may be embodied in other forms of sole-pressing machines,broadly defined in the claims. lt is also to be understood that exceptwhere such limitations are expressly stated in the claims the presentinvention is not limited to any specific construction or arrangement ofparts.

The machine illustrated in the drawings is provided with twoshoe-supporting jacks and with two cooperating sole-pressing forms, theacks being indicated at 1 and the forms at 2. Each jack is constructedto receive a shoe-supporting last or follower 3 and is mounted toreciprocate in a horizontal guideway formed in the upper portion of atable 4, mounted to reciprocate vertically in guideways on the mainframe of the machine. The jacks when connected to their actuatingmechanism are reciprocated on the table 4 by means of levers 5, pivotedat their lower ends to brackets projecting from the lower end of theslide which carries the table 4 and connected at their upper ends to thejacks by means of links 6, a lever and link being provided for each jackand the levers being mounted to move independently of each other, sothat one jack can remain in a pos1- tion of presentation while the otherjack is being moved into a position to cooperate with a sole-pressingform and returned to its position of presentation.

The levers 5 are oscillated by means of links or latches 7, providedwith slots 8 in their forward ends,

adapted to engage studs on the levers, and l the machine to a po--pivotally connected at their rear ends to a lever 9, pivoted upon theframe of the machine and provided with a cam-roll engaging a cam on acam-shaft 10. Both latches 7 are connected to a lever 9, so that theymove in unison, and in order to permit either jack to be moved while theother jack remains in its position of presentation vertical rods 11 aremounted to reciprocate in guideways on the slide which carries the table4 and are provided with sleeves 12, having projections extending beneaththe latches 7. A rod 11 is provided for each latch, and the rods areheld normally in a position in which the latches 7 are disconnected fromthe levers 5 by means of sprin s 13, coiled around the rods andinterpose between the lower bearings for the rods and the sleeves 12. Attheir lower ends the rods are provided with arms 14, projecting beneathtreadles 15, pivoted in the lower portion of the machineframe and actingwhen depressed to throw the cam-shaft into operation, as will behereinafter described. A treadle 15 is provided on each side of themachine, and a depression of a treadle acts to depress the rod 11 on thesame sideof the machine and permit the latch 7 on that side of themachine to engage a lever 5.

The requisite amount of pressure to level the sole of a shoe supportedupon a jack is produced by the upward movement of the table 4 when thejack is in position beneath its operating-form. The table 4 is actuatedat the proper times during the operation of the machine by mechanismcomprising a cam on the cam-shaft 10, a toggle-lever 16, and a link 17*,connecting the toggle-lever and cam.

To automatically regulate the amount of pressure applied to the sole ofa shoe, the forms 2 are mounted upon a cross-head 17 and mechanism isprovided for permitting the cross-head to descend until a form is seatedupon the sole of a shoe for locking the crosshead'in position duringtheupward movement of the table 4 and for raising the crosshead after thesole of the shoe has been leveled. The forms 2 are'removably secured toform-carriers 18, being held in position there on by means oflocking-pins 19, mounted in the form-carriers and engaging holes in thestraps secured to the forms, and the formcarriers are supported from thecross-head 17 so as to be capable of a slight rocking movement, as iscommon in this class of machines. The mechanism for permitting thecross-head 17 to descend and seat a form upon the sole of a shoe and forraising. the cross-head after the sole of a shoe has been leveledcomprises a cam on the cam-shaft 10, a lever 20, pivoted at its rear endto the frame of the machine and provided at its forward end with a rollbearing against the cam, and a link 21, connecting the front end of thelever and the cross-head. For locking the cross-head 17 in positionduring the upward movement of the table 4 locking-cams 22 are providedsecured to a rock-shalt 23, mounted in the frame of the machine abovethe cross-head 17, which cams are adapted to be swung inwardly over thecross-head until they contact therewith and to be swung outwardly toallow the cross-head to be raised. The cams 22 are swung inwardly by theforce of a spring 23*, (see l ig. 2,) connected to a lever 24 and areswung outwardly by mechanism comprising a cam on the cam-shaft 10, thelever 24, pivotally mounted at its rear end upon the frame of themachine and provided at its forward end w ith a roll engaging the cam,and a link 25, connecting the rorward end of the lever 24 to an arm 26,securedto the rock-shaft 23 and projecting rearwardly therefrom.

The cam-shaft 10 of the machine is driven from the main driving-shaft 31by connections comprising a worm-wheel 27 on the cam-shaft, a worm 28,meshing therewith, a shaft 29, to which the worm is secured, and spiralgears connecting the shaft 29 and c living-shaft 31. A driving-pulley 32is mounted to rotate loosely on the drivingshaft 31, and afriction-clutch is provided for connecting the pulley to the shaft whenthe machine is to be thrown into operation. The friction-clutch consistsof two members, one of which is formed on the pulley and the other ofwhich (indicated at 33) is rigidly secured to the driving-shaft, so asto rotate therewith. To connect and disconnect the driving-shaft andpulley, the pulley is moved longitudinally on the shaft. Theclutclnactuating mechanism for moving the pulley com prises a cam 34,secured to the cam-shaft 10 outside of the worm-gear 27, a sleeve 35,provided with an upwardly-extending arm 36 and a downwardly extendingarm 37, a rod 38, mounted to rock and move longitudinally in bearingssupported from the frame of the machine, a spring 39, surrounding therod and interposed between the sleeve 35 and one of the bearings for therod, a lever 40, pivotally mounted in the rear portion of the frame ofthe machine and connected at one end to the rear end of the rod 38 bymeans of pins projecting from the forked end of the lever into a groovedblock 41, secured to therod, an arm 42 rigidly connected to the lever40, a lever 43, connected at one end to the hub of the driving-pulley bymeans of pins projecting from its forked end into agroove in the hub,and a rod 44, connecting the other end of the lever 43 and the arm 42.When the machine is at rest, it ith both of the jacks at the front ofthe machine in their position of presentation, the parts of theclutch-actuating mechanism are in the position illustrated in Figs. 1and 3, the arm 36 of the sleeve 35 being engaged by one of theprojections on the cam 34 and the rod 38 being held in the position towhich it has been moved by the cam against the force of the spring 39.To start the machine, the arm 36 is swung inwardly bythe operatorthrough.

means to be hereina;ter described and is thereby moved out of engagementwith the projection on the cam 34. As soon as the arm 36 moves out ofengagement with the projections on the cam 34 the rod 38 is moved to theleft by the spring 39 and through the connections above described thedriving-pulley 32 is moved into engagement w ith the clutch member 33.The driving pulley remains in engagement with. the clutch member 33until the cam-shaft 10 has made one-half of a revolution, at which timethe other projection on the cam engages the arm 36, and the rod 38 isreturnedto the position indicated in Fig. 1, thereby moving thedriving-pulley out of engagement with the clutch member 33. The arm 36after being moved inwardly out of engagement with a projection on thecam 34 is returned'into the path of movement of the other projection bymeans of a spring 45, acting on the lower end of the arm 37, as bestshown in Fig. 5.

To stop the rotation of the drivingshaft as soon as the drivlng-pulleyis disconnected therefrom, a friction-brake 46 is provided, which isactuated from the lever 40, as indicated in Figs. 2 and 3.

The projections on the cam 34 of the clutch-actuating mechanism are solocated that the driving-pulley is disconnected from the driving-shaftwhen a jack and form are in a position of pressure and again when thejack has been returned to its position of presentation. As has beenstated, the arm 36 is moved inwardly out of engagement with the cam 34by the operator in order to connect the driving shaft and pulley whenboth jacks are in a position. of presentation. When a jack and form isunder pressure, the arm 36 is also moved inwardly to connect the drivingshaft and pulley; but this movement of the arm is produced automaticallyby means of a timing mechanism driven from the drivin -pulley. Thistiming mechanism is best il ustrated in Figs. 3, 4, and 5. Referring tothese figures, 47 indicates a spiral cam or worm secured to a shaft 48,journaled in the lower portion of the machine-frame and constantlyrotated from the pulley 32 by means of a chain passing oversprocketwheels 49 and 50, secured, respectively, to the hub of thepulley and a shortshaft 51, spiral gears 52 connecting the shaft 51 anda shaft 53 and bevel-gears 54 connecting the shaft 53 and the shaft 48.Parallel to the shaft 48 a rod 55 is mounted in the frame of the machine, so as to be capable of moving longitudinally, and upon this rodis pivotally mounted a tripper 1n the form of a lever 56, the inner endof which is provided with a series of teeth 57, adapted to mesh with theworm 47, and the outer end of which is provided &

with a notch 58, through which the lower 1 end of the arm 37 of theclutch-actuating mechanism projects. The tripper 56 is acted upon by acoiled spring 59, which tends to I hold the teeth 57 in mesh with theworm 47. l Normally the tripper is held in a position in which the teeth57 are out of engagement 1 with the worm 47 by means of a latch 60, theI lower end of which is held in engagement with a projection 61. on thetripper by means of a spring 62, acting on the upper end of the latch.Upon the worm-gear 27 an arm 63 is secured, (see Figs. 1 and 2,) andthis projection is so arranged that it comes into engagement with theupper end of the latch and moves the latch to release the tripper56justbefore or at the time that the cam-shaft is stopped with the jackand form in a position of pressure. As soon as the tripper 56 isreleased it is moved by the spring 59 to bring the teeth 57 intoengagement with the worm 47, and while the teeth remain in engagementwith the worm the rod 55 is moved l longitudinally, and the outer end ofthe tripper 56, bearing against the arm. 37 of the clutch-actuatingmechanism, moves this I arm outwardly and the arm 36 inwardly, until thearm 36 is removed from engagement with the cam 34 and the clutch-actuat-I ing mechanism acts to connect the driving l I shaft and pulley. Whenthe clutch-actuating mechanism thus acts, the rod 33 and the arms 36 and37 carried. thereby move toward the left, as viewed in Fig. 1, and thearm 37 acts on the tripper 56 to swing it about its pivot to a positionin which the teeth 57 are out of engagement with the worm 47, in whichposition it is locked by the latch 60. As soon as the trippcr isdisconnected from the worm 47 the rod 55 is returned to its initialposition by the action of the spring 45.

The initial position of the rod 55 determines the length of time duringwhich the camshaft remains at rest with the jack and form underpressure. To enable this time to be varied as desired, an adjustablestop 64 is l provided, which is arranged in the path of l movement of anarm 65, secured to the rod 1 55. The stop 64 is mounted upon the shaft48 and upon a shaft 66, which forms the pivotal support forthestarting-treadles 15, and to enable the stop to be convenientlyadjusted by the operator it is connected, by means of a rod 67, to thelower end of an arm 68, secured to a short rock-shaft 69, to whichrock-shaft an adjusting-lever is secured. The adjusting-lever 70 islocated at the front of the machine in convenient position to be graspedby the operator and is provided at i its upper end with a locking-pinwhich coop- J erates with a series of holes in an indicatorl plate tolock the stop 64 in adjusted position.

To enable the cam-shaft 10 to be thrown I into operation by the operatorafter the driv ing-pulley has been disconnected from the l driving-shaftwith both jacks in a position of presentation, the rear ends of thetreadles 15 are shaped as illustrated in the drawings to cooperate withblocks 71, secured to the rod 55, the shape and arrangement of the rearends of the treadles and the blocks being such that a depression ofeither treadle moves the rod 55 longitudinally a sufficient distance tothrow the clutch-actuating mechanism into operation.

In the machine illustrated in Figs. 1 to 5 and above described it willbe noted that when a treadle 15 is depressed to throw the cam-shaft intooperation the corresponding latch 7 is moved into engagement with alever 5 solely by the force of gravity, the movement of the latch intooperative position being permitted by the downward movement of the rod11 associated therewith, the sleeve 12 of which normally holds the latch7 raised. In the use of the machine in actual practice trouble has beenoccasioned by frequent failure of the latch 7 to move a sufiicientdistance to firmly engage a lever 5, the latch resting insecurely on thecross-pin on the lever and being disengaged therefrom before the jackhas completed its inward movement. As a result the jack is not broughtinto alinement with its cooperating form, and during the upward movementof the table 4 an excessive pressure is brought upon the jack and formwhich'is often sufficient to break the shoe-supporting follower or lastand injure other portions of the machine. Also in the operation of themachine both latches 7 are not always raised completely out ofengagement with the levers 5 when the jacks are in their position ofpresentation, and as a consequence both jacks are occasionally connectedto the actuating mechanism when the machine is thrown into operation, orthe jack which should remain in a posititn of presentation is displaced,so that the manipulation of the shoes by the operator is interfered withand the follower or last on the jack is injured during the upwardmovement of the jack-supporting tab e. I

The present invention is designed, primarily, to overcome these defectsin the construction and operation of the machine, the preferredembodiment of the invention being illustrated in Figs. 6 and 7. Asillustrated in these figures, each latch 7 is provided with a curvedslot 72, which slots are engaged by pins or rolls 73 upon opposite endsof a rock-shaft 74, journaled in a bracket 75, secured to thereciprocating slide, which carries the table 4. The pins or rolls 73 arearranged upon opposite sides of the axis of the rock-shaft, so that amovement of the rockshaft moves the latches positively in oppositedirections. Near its ends the rcck-shaft is provided withoppcsitely-extending arms, c which are connected, by means of links 76,to

, otally mounted the treadles 15, the arrangement being such that whenone treadle is depressed the shaft 7 4 is rocked in one direction andwhen the other treadle is depressed the shaft is rocked in the oppositedirection. A depression of either treadle therefore acts to positivelymove the corresponding latch 7 into operative position and the otherlatch into inoperative position. Before the cam-shaft can be stoppedeither with a jack and form in a position of pressure or with both acksin a position of presentation the treadle 15, which has been depressed,must be raised, and this is accomplished by means of springs 77,connected to the treadle, as indicated in Fig. 1. To allow the treadlewhich has been depressed to rise without actuating the latches, thelinks 76 are connected to the treadles by pin-and-slot connections, asillustrated in Fig. 6, which connections afford a sufficient amount oflo st motion between the links and the treadles to allow the depressedtreadle to rise and also the actuation of the latches by the depressionof one of the treadles without producing any movement of the othertreadle.

In the machine illustrated in Figs. 1 to 5 the rods 11, in addition toferming a connection between the treadles and the latches, are alsoutilized to lock the jacks in their position of presentation, the upperends of the rods entering recesses in the jacks when the jacks reach thelimit of their outward movement and being held depressed by contact withthe lower surface of the jacks during the inward and outward movement ofthe jacks. The means for locking the jacks in their po sition ofpresentation is thus connected to the means for actuating the latches,and the operations of the locking means and the latches are dependentupon each other. In Figs. 6 and 7 an improved means for locking thejacks in their position of presentation is illustrated, which operatesindependently of the latches, and this locking means constitutes afeature of the present invention. As illustrated, the locking meansassociated with each jack consists of a spring-pressed plunger 78,mounted in the slide carrying the jack-supporting table 4. At its upperend the plunger 78 bears against a latch 79, pivin a recess in the table4 beneath the jack. At its inner end the jack is cut away on its undersurface, as indicated at 80 in Fig. 6, to form a shouldered recess intowhich the latch 79 is pressed by the plunger when the jack reaches itsposition of presentation. The engagement of the latch with theshouldered recess is sufficient to hold the jack in its position ofpresentation while the operator is performing any operations upondepressed until the jack is again returned to its position ofpresentation. The interposition of the pivoted latch. 79 between theplunger 7 8 and the lower surface of the jack avoids undue frictionbetween the plunger and the jack or excessive wear and at the same timeprovides a simple and efficient' means for locking the jack in aposition of presentation.
